Wish I had seen this thread earlier before I just went to automatically purchase the WeatherTech Floorliner HP. Paid through the nose, but since it is my wife's car, I thought I had better get the WeatherTech because it was what she was used to. It turns out the WeatherTech only covers about 3/4s of the the dead pedal.
The HP seems to be a little heavier, in that there are more ribs and nibs. The 2021 HP mats shown below in this US spec 2021 CX5.
1. Passenger front backside with ribs and nibs
2. Driver front showing toned down logo and half dead pedal coverage
3. Passenger front
4. Rear mat, from passenger side.
The trunk mat is still in shipment somewhere. It may not be as good as the Mazda OEM mat in that it does not have cut outs for the cargo hooks or the triangular fold back flaps for the rear mini storage compartments. WeatherTech does have a higher lip, though. I have to decide, when it comes, whether I want to return it and use Mazda OEM trunk liner. I was pretty happy with the Mazda OEM trunkliner in the Mazda 6, although it did not have as high a sides nor as tough a material.
